The context token is used to create the model and also to look up the best tag once the model is created. Also demonstrates an effective use case of this interface by showing how to leverage it to build a Python language model server.

Note that we ignore all casing information when computing the unigram. This is explained graphically in the above diagram also. UnigramTagger inherits from NgramTagger which is a subclass of ContextTagger which.

The Natural Language Toolkit has data types and functions that make life easier for us when we want to count bigrams and compute their probabilities. Import collections nltk we first tokenize the text corpus tokens nltkword_tokenizecorpus here you construct the unigram language model def. Listing 2 shows how to write a Python script that uses this corpus to build a very simple unigram language model.
